Skinceuticals CE Ferulic, $165, continues to be the gold standard antioxidant serum. It's simple yet potent — the vitamin E and ferulic acid help keep the high concentration of vitamin C stable and active. The Skinceuticals scientists recently concluded a massive pollution study and found that an antioxidant serum paired with a sunscreen will significantly protect skin from ozone pollution — the worst kind for aging. Without adequate antioxidant protection, however, pollution exposure is just as damaging as UV — if not worse.
